Nobel Prize goes to scientists behind mRNA Covid vaccines 0
The Nobel Prize in Physiology or Medicine has been awarded to a pair of scientists who developed the technology that led to the mRNA Covid vaccines.
Professors Katalin Kariko and Drew Weissman will share the prize.
The technology was experimental before the pandemic, but has now been given to millions of people around the world to protect them against serious Covid-19.
The same mRNA technology is now being researched for other diseases, including cancer.
The Nobel Prize committee said: “The laureates contributed to the unprecedented rate of vaccine development during one of the greatest threats to human health in modern times.”
Both were told they had won by telephone this morning and were said to be “overwhelmed”.
Vaccines train the immune system to recognise and fight threats such as viruses or bacteria.
Traditional vaccine technology has been based on dead or weakened versions of the original virus or bacterium – or by using fragments of the infectious agent.
In contrast, messenger ribonucleic acid (mRNA) vaccines use a completely differently approach.
During the Covid pandemic, the Moderna and Pfizer/BioNTech vaccines were both based on mRNA technology.
Professor Kariko and Professor Weissman met in the early 1990s when they were working at the University of Pennsylvania, in the United States, when their interest in mRNA was seen as a scientific backwater.

Mali redeploys troops to rebel stronghold 0
The Malian army began redeploying troops on Monday towards the northern rebel stronghold of Kidal, two security officials said, amid a resumption of hostilities in the region.
“As part of the reorganisation of our arrangements in the north, we have begun the redeployment of our forces in the northeastern region of Kidal,” a Mali military official who spoke on condition of anonymity told AFP.
A convoy left the northern city of Gao, which lies 300 kilometres (185 miles) southwest of Kidal, early Monday, the source added.
Another security official said the convoy was made up of 119 vehicles and was currently stopped on the road to the north of Gao.
National security chiefs made the deployment decision at a meeting late on Sunday, he added.
Kidal is a crossroads region in the north that is not under the control of the Malian state but of a coalition of predominantly Tuareg groups called the Coordination of Azawad Movements (CMA).
Since the end of August, the north of Mali has seen a resumption of hostilities by the CMA and an intensification of jihadist attacks against the army.
The fact that Kidal is still controlled by the ex-rebels continues to pose a sovereignty issue and remains a source of irritation for Bamako, including for the junta.
Military leaders have made re-establishing state control across the whole country one of their main messages.
